Abstract

A graphite (carbon) composite solid electrode, prepared from graphite powder and epoxy resin, was used as a working electrode for anodic stripping voltammetry. The underpotential deposition effect, which appears at metallic electrodes, was clearly observed on this type of electrode as well. In the case of a simultaneous deposition of two metals on the surface of the composite solid electrode, the anodic dissolution of the metal, which is anodically dissolved at more negative potentials, is substantially influenced by the presence of the other deposited metal. This effect was exploited for the determination of lead in the presence of other metals by differential pulse anodic stripping voltammetry. The article presents possible applicability of such a type of very simple composite electrode to studies of the underpotential deposition effect as well as for analytical purposes.
